Efficient Brownian dynamics simulation of particles near walls. II. Sticky walls.
In this paper we treat a boundary condition, the "sticky boundary," which appears to be quite useful in mesoscopic models. The sticky boundary is modeled as an infinitely deep, infinitely narrow, potential well adjacent to a reflecting boundary. The free energy corresponding to this boundary is finite. The boundary condition, which can be viewed as an intermediate between the absorbing and refl...
متن کاملEfficient Brownian dynamics simulation of particles near walls. I. Reflecting and absorbing walls.
In this paper a method of numerically handling boundary conditions within Brownian dynamics simulations is discussed. The usual naive treatment of identifying reflection or absorption processes by checking for boundary crossings yields O(sqrt[deltat]) discretization errors. The method we propose here yields O(deltat) errors, similar to the case of Brownian dynamics without wall interaction. The...
متن کاملBrownian dynamics of a sphere between parallel walls
– We describe direct imaging measurements of a colloidal sphere’s diffusion between two parallel surfaces. The dynamics of this deceptively simple hydrodynamically coupled system have proved difficult to analyze. Comparison with approximate formulations of a confined sphere’s hydrodynamic mobility reveals good agreement with both a leading-order superposition approximation as well as a more gen...
متن کاملUnravelling turbulence near walls
Turbulent flows near walls have been the focus of intense study since their first description by Ludwig Prandtl over 100 years ago. They are critical in determining the drag and lift of an aircraft wing for example. Key challenges are to understand the physical mechanisms causing the transition from smooth, laminar flow to turbulent flow and how the turbulence is then maintained. Recent direct ...
متن کاملModeling of Polymer Flow Near Solid Walls
Polymers are known to exhibit various flow instabilities during extrusion in which a molten polymer is forced to flow through a narrow die, in order to form a strand or acquire a desired shape of the final product. Recent developments in experimental techniques revealed that some of the instabilities are interfacial in nature, that is originate from the violation of the no-slip boundary conditi...
